Myntra.com — Myntra account terminated

Suddenly I am not able to login to my account and getting an update as account does not exists. When I raised a complaint they are saying account has been terminated. But without any reason or evidence how they can update that account is terminated. This is simply a fraud to cover up some big issues happening with our account. I have been a regular customer to Myntra and had gathered certain points and was an elite customer. Its not acceptable that they simply terminate our account without any reason.
